ORNAMENTALCHAIN.

SPECIFICATION forming part of Letters Patent No, 293,417, dated February 12, 184. Application filed November 13,1882. (No model.)

To @ZZ whom, it may concern:

Be it known that I, HENRY A. CHURCH, of the city and county of Providence7 and State of Rhode Island, have invented a new and useful Improvement in Ornamental Chains; and I hereby declare that the following is a full, clear, and exact description ofthe same, rei erence being had to the accompanying drawings, form part of this specification.

This invention has reference to an improvement in that class of ornamental chains known in the art as roller-chains-that is to say, a chain made up by securing a large number Vof 'small rings or units side by side to form the width required, each set of which overlaps the next set lengthwise.

The invention consists in providing the units 'with two or more holes through which the binding-wires pass, so as to secure the same together and prevent the units from turning,

- and in the peculiar and novel construction of n represents a number of the central units provided with two or more holes, or holes of such form as will iirmly hold the units on the binding-wires. Fig. 7 is a sectional view of one form of a modification. Fig. Sis another form of a modification, in which the binding-wires' are secured to the cap instead of to the units, and the unit is placed over the cap. Fig. 9 is a sectional view of a side unit on which a washer is secured', having two slots on opposite sides, through which the legs of the staplepass. rIhe washer, with the staple, is secured by closing theunit in a die, so as to retain the washer. Y

In roller-chains, when the chain is made up and colored, it requires to be polished. In polishing, the portions of the units exposed willreceive a fine polish, while the portions of the units out of the reach of the polishing device are not so polished. As long as the units remain in the position in which they were when polished, the appearance of the chainis preserved. As soon, however, as the units or any of them are partially turned, the appearance of the chain is injured by presenting in places the unpolished surface of the units.

Y I am aware that such units have before my present invention been provided with elongated holes, for the purpose of better securing the same against rotation, as is shown and described in Letters Patent No. 241,189, granted to me May 10, 1881. The first part of my present invention refers to holes constructed to iixedly hold' the units, in which the wires nearly fill the holes or the ends of the holes, as I nd in practice that an elongated hole may allow sufcient playto expose small portions-of the units not polished.

In the drawings, A A are the central units; n

B B, the side units; C C, the caps secured in one set of the side units, so that the same correspond in appearance with the side'units on the opposite side of the chain.

d dare wire loops or staples, which are secured within the closed side units, B, Vby so1- der, so that the two legs of the -staples project. They are inserted into the .holes formed in the central units, A A, and then pass through holes formed in the end units, and are secured by twisting the ends of the staples together, as

shown in Fig. 2; or the ends of the staples are passed through holes formed in the caps C and the ends twisted together, when the unit is se cured over the cap, as is shown in Figs. 7 and S. In either case the form and appearance of -the side unitsV on both sides of the chain correspond.

The side units, B B, as well as the caps C C, for closing the units, may be ornamcnted by stamping in various ways, as is shown in Figs.

LLand 5.

The caps C C may be secured by pressing the metal of the units around the cap, or by securing the same with solder.' 4 The form ofthe cap and the unit when united must be of the same appearance and outline as the closed unit on the opposite side, so as to make both sides of the chain alike.

The'holes e e may be formed in the central units separate or connected by a slot or other opening, as is shown in Fig. 6, but should be of such form as to nearly iit the wire, so that Ioo the units cannot turn and expose the unpolstaples, of the closed units B, the edge-cups ished portions af the units. provided with the caps C, and the staples d,
